The video there says "after about an hour and a half meeting between lawyers for all sides, an agreement was reached. The girl's parents agreed to let her continue carrying the baby, and they gave her permission to marry the child's father."

And Baptist Press says it has details of the agreement:

The parents of both teens agreed in the final order to equally share financial responsibility for medical care related to the pregnancy. If the teens get married the financial burden will fall to them.

R.E.K.'s parents, the defendants in the case, gave "irrevocable consent" for their daughter to marry the father of her baby. Under a 2005 Texas law, teens as young as 16 can marry with parental consent.

R.E.K., who had lived with her boyfriend's parents for several months prior to this case, now lives with her mother. Under the ruling, R.E.K. must maintain a "B" average in school in order to have unrestricted use of her vehicle.
